On crystal size and cooling rate
Journal of Microscopy, 1986SUMMARYA theoretical model is proposed which is used to derive a quantitative relationship between the critical cooling rate and average crystal size at any location within a biological specimen of given shape subject to rapid freezing. The model is applicable to the slamming, plunging or spraying methods of cryofixation provided the ice crystal size ...

Cooling rate affects rhesus monkey sperm survival
Journal of Medical Primatology, 2012AbstractBackground The rate at which lethal intracellular ice formation occurs during cryopreservation is highly dependent on several variables. The objective of this study was to determine the optimal rate at which rhesus sperm can be cooled.Methods Experiments were performed using three rates of cooling.

Annealed importance sampling with constant cooling rate
The Journal of Chemical Physics, 2015Annealed importance sampling is a simulation method devised by Neal [Stat. Comput. 11, 125 (2001)] to assign weights to configurations generated by simulated annealing trajectories. In particular, the equilibrium average of a generic physical quantity can be computed by a weighted average exploiting weights and estimates of this quantity associated to ...

Exercise heart rate response to facial cooling
European Journal of Applied Physiology and Occupational Physiology, 1981The heart rate responses of physically untrained men to exercise with and without facial cooling were determined. Cold wind (10 degrees C, 6.5 m x s-1, or 2 degrees C, 6.5 m x s-1) was directed at the faces of the subjects during a 16 min bout of progressively intense exercise.

Early-postmortem cooling rate and beef tenderness
Meat Science, 1980Four distinct early-postmortem cooling rates (as measured within the longissimus muscle) were obtained by exposing one side of each of five fat and five lean steers to moving air at -2° and the other to 9° static air. Loin steaks of the fastest cooling group were found to be the least tender and to have the shortest sarcomeres; the three remaining ...

Cryobiology, 2003
The purpose of this work was to study cell viability as a function of cooling rate during freezing. Cooling rate strongly influences the viability of cells during cold thermal stress. One of the particularities of this study was to investigate a large range of cooling rates and particularly very rapid cooling rates (i.e., faster than 20000 degrees C ...

Scanning microcalorimetry at high cooling rate
Thermochimica Acta, 2003Abstract Heat capacity measurements at fast cooling and heating were realized for linear polyethylene NBS SRM (standard reference material) 1484 sample, ca. 120 ng, in the melting-crystallization region. A commercial vacuum sensor, thermal conductivity gauge TCG-3880, Xensor Integrations, was utilized as a cell for a micro-calorimeter suitable for ...
